PROCESS OF MAKING FLOOR AND CEILING PLATES.

Specification of Letters Patent.

Patented Oct. 31, 1911.

Application filed January 10, 1911. :Serial No. 601,923.

To all whom it may concern Be it known that I, ALLAN J. BEATON, a citizen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in the Process of Making Floor and Ceiling Plates, of which the following is a specification.

My invention relates to improvements in the process of making floor and ceiling plates, and the objects of my improvements are simplicity, economy and efiiciency in production, and to produce a superior finished product.

In the accompanying drawings :Figure 1 is a plan view of my floor and ceiling plate. Fig. 2 is a reverse plan view of the punched blank for the right body part, ready for forming. Fig. 3 is a similar view of the blank for the left body part. Fig. 4: is a similar view of the parts shown in Figs. 2 and 3 in position for forming the lines of bending being indicated by broken lines. Fig. 5 is a similar view of the same parts after forming the original outline being indicated by broken lines. Fig. 6 is a side elevation of the left body part as viewed from the side that abuts with the mating right body part. Fig. 7 is a bottom view of the punched blank for the left locking plate, before forming. Fig. 8 is a similar view of the right locking plate. Figs. 9 and 10 are similar views of the parts shown in Figs. 7 and 8 after forming. Fig. 11 is a similar view of the same after being united by a hinge joint and with the latch members engaged. Fig. 12 is a similar View of my floor and ceiling plate.

My process is particularly applicable to; the production of floor and ceiling plates; such as shown and described in my applicai tion for patent, Serial No. 507,518, filed:

July 14, 1909. As shown in the said applij cation, my floor and ceiling plate comprises two parts, respectively a left part A and a right part B, forming an annular ring in-.

closing a central opening C adapted to receive a pipe, the said parts being united at one end by a hinge E and at the other end by a latch F, and they are provided with supporting springs D suitable for engaging with the said pipe, when in position in the said central opening C so as to support the said plate. The said left part A and right part B are each composed of an outer body part and an inner locking plate, all formed of sheet metal and united by integral lugs. In Figs. 2 and 3 are shown the punched blanks for the said body parts of the said right part B and left part A and comprising generally semi-annular members respectively '11 and 12, thelines of abutment 13 and 13 being generally straight and along a diameter, except adjacent the hinge end where the said blanks are suitably curved as shown at 13 and 13 so as to provide contiguous edges permitting of free relative turning of the parts when united by the said hinge joint E, the said curved edges being generally concentric with the axis of the said hinge joint. The said abutting straight line formation 13 and 13 is interrupted by the central opening C and C of semicircular outline, the inner periphery of which comprises material for providing a turned edge 22, and integral therewith are, as shown in the blank, inwardly directed lugs comprising a pair of main lugs 17 adjacent the body ends and a pair of spring holding lugs 18, the edge 22 between the said lugs 17 and the ends being reduced to receive a lug 26 on the locking plate to be described, as shown at 41, Fig. 4. The said spring holding lugs 18 have a spring receiving space 19, limited by a .back wall 20 and an overhanging edge 21. The two punched blanks 11 and 12 shown and described are dished and are formed by a single operation and by a single set of dies to give the desired contour which comprises dish-ing the parts generally, forming the said turned edge 22 and at the same time positioning the lugs described suitably for receiving the locking plates to be described and being finally bent over into the securing position for holding the locking plates within the body parts.

The blanks shown in Figs. 7 and 8 for my left and right locking plates comprise generally semi-annular members provided on one end with hinge members that form the said hinge E and at the other end with latch members to form the said latch F, and intermediate the said hinge members and latch members generally fit the interior of the said body parts 11 and 12, particularly along the inner edge 27 the body ends being provided with the said lugs 26 which project inwardly from the said inner edge 27. Midway between the said ends,however, the periphery recedes as shown at 28 so as to provide an integral central spring lug 30 which when finally bent up will form. a stop to receive the apeX of the supporting spring D. The said hinge members comprise overhanging ears bent away from the general surfaces of the locking plates, the ear 31 on the left locking plate 2-1 overlapping the ear 32 of the right locking plate 25, the means of pivotal attachment shown comprising a hollow rivet 33, formed integral with the said left hand member engaged with an eye or hole 34: in the right hand member. The said latch member comprises stop lugs 36 on the end of the left hand locking plate 24:, shown as projecting beyond the end of the blank, bent upwardly so as to form rigid stops for engaging notches 37 in the spring latch member 33 which is integral with the said right locking plate 25 and overhangs the end of the same. The said supporting springs D comprise U-shaped springs of flat spring material of width to fit the said spring receiving space 19 and having arms 39 of length sufficient to overhang the said central space C with the inside of the apex in abutment with the said back spring lug 30 and the said arms in the said receiving space 19. Accordingly, the shaping or forming of the said locking plates from the blanks shown in Figs. 7 and 3 comprises as regards the left locking plate 24: giving right upward bends to the stop lugs 36 of the latch and the back spring lug 30 and upsetting the ear hinge 31, and as regards the right locking plate 25 comprises a similar bending of the back spring lug 30, upsetting the hinge ear 32 and giving a slight upward bend to the outer extremity 4.0 of the said spring member 38 of the latch F so as to be self engaging with the said stop lugs 36. The integral rivet 33 may be formed either before or after the shaping of the locking plate.

The assembly of the locking plates comprises the completion of the hinge connection E by heading over the rivet 33 after being engaged with the said eye 3 1. The assembly of the locking plates 24: and 25 hinged as described with the said body parts 11 and 12 consists in placing the said locking plates in position within the said body parts, so as to form essentially a lining or reinforcement of the interior, the said edge 27 of the locking plates abutting the said turned edge 22 of the body parts, the said stop lugs 26 abutting the said main lugs 17, and turning the said main lugs 17 over against the face of the said locking plates 24 and 25. The springs D are finally placed in position in engagement with the said spring holding lugs 18, and back spring lug of the coacting parts, and when united,

forming an exterior with parts in relative alinement such as to conform essentially to that of a single part or one piece plate. Important features in producing this result are the production of proper mating abutting edges of the body parts and insurance that the same will be brought correctly to the abutting position, all of which features are effected by the process described. The production of proper mating abutting edges of the body parts mentioned is due to the fact that during the shaping of the said body parts 11 and 12 as a unit as described the abutting edges 13 and 13 of the same are driven one against the other under pressure and the insurance that they will be brought correctly to the abutting position under normal conditions of use is due to the fact that the hinge members are secured to the body parts while the latter are held together cor rectly as regards the abutting of the mating edges.

I claim as my invention:

The process of making floor and ceiling plates composed of mating members of sheet metal comprising a pair of body parts of sheet metal and having edges in abutment during normal usage and combining to form an annular plate having a generally rounded or convex contour, involving punching out a pair of blanks, one for each of the said body parts, placing together the edges that come into abutment in the said annular plate and shaping the two blanks essentially as one combined blank by one set of dies and in one operation, whereby the said abutting edges are forced together under pressure and so as to insure a fitting together of the said edges.
